Commuters Monday morning are in for blizzard-like conditions while driving to work, forecasters said, with as much as 8 inches of snowfall in Suffolk and 4 inches in Nassau.

The National Weather Service on Sunday issued a winter storm warning in effect from 3 a.m. to 6 p.m. Monday — with the heaviest snow to fall during the morning commute.

The warning also calls for northeast winds gusting up to 35 mph and “blizzard conditions” at times. It said there will be “heavy wet snow” that may cause the downing of power lines.

There is a winter weather advisory for the same period for Nassau, with the service forecasting 2 to 4 inches there and winds of up to 30 mph. A county spokesman said Nassau would spray brine on Nassau roads in the morning.

This will be the first of at least two systems moving through the region this week, the service said, with a second one coming through Monday night into Wednesday afternoon.

An additional 3 to 5 inches could accumulate in both counties during this second storm.

Officials representing several Nassau and Suffolk school districts said there were no plans in place Sunday to alter class schedules.

According to the National Oceanic and Atmospheric Administration, “In general, [there is] moderate to high confidence for a prolonged period of unsettled weather with intermittent light snow from late tonight through Wednesday,” NOAA spokesman Peter Wichroski said in a statement Sunday morning.

Monday will be in the mid-30s and lows in the mid 20s.

Tuesday, highs will be in the mid-30s and lows again will be in the mid-20s.

Wednesday’s highs are expected in the upper 30s and lows in the mid-20s.

“On Thursday we’ll finally see Sun again, but it’ll be cooler with highs in the low 30s and lows around 20,” NWS meterologist Faye Barthold in Upton said. “It looks dry.”

Friday will be “very similar,” Barthold said. Highs will be in the low 30s but at night temperatures will take a sharp drop into the upper teens.
